Can someone share a bit of info on the original Racing Jackets (the old,non-foldable version which were in production prior to the current Jawbone/Racing Jacket version)? - How is the fit (tight/loose) - suits bigger head or slimmer face? - Do they sit securely or do they bounce if you do sports? - How is the quality of the nose pieces? - How is the field of vision considering the full frame? Any other things to note? Thanks guys !
